A Korean team fabricated a novel metamaterial with an index of refraction of 38.6 which is considered the most extreme positive value. In this paper, we employ the new metamaterial to construct a binary photonic crystal having the structure air/(metamaterial/SiO 2 ) N /Si. The binary photonic crysta...
